Systems and methods for predictive scanning and handover are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive context information; predict a loss of a first wireless connection based upon the context information; in response to the prediction, start scanning for a second wireless connection while maintaining the first wireless connection; and switch to the second wireless connection prior to losing the first wireless connection.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An Information Handling System (IHS), comprising: a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive context information comprising at least one of a first user application or a second user application currently under execution by the processor; determine that the IHS is moving toward a dead zone with respect to a first bidirectional wireless connection using the context information; predict a loss of the first bidirectional wireless connection based upon a first threshold distance or time associated with the first user application or a second threshold distance or time associated with the second user application, wherein the first threshold distance or time is different than the second threshold distance or time; in response to the prediction, start scanning for a second bidirectional wireless connection while maintaining the first bidirectional wireless connection; and switch to the second bidirectional wireless connection prior to losing the first bidirectional wireless connection.
2. The IHS of claim 1 , wherein the IHS comprises a mobile device.
3. The IHS of claim 1 , wherein the first bidirectional wireless connection is a WiFi connection, and wherein the second bidirectional wireless connection is a cellular connection.
4. The IHS of claim 1 , wherein the context information comprises a Received Signal Strength Indicator (RSSI).
5. The IHS of claim 1 , wherein the context information comprises a Time-of-Flight (ToF) indicator.
6. The IHS of claim 1 , wherein to determine that the IHS is moving toward the dead zone, the program instructions, upon execution, further cause the IHS to compare a current behavior of a user of the IHS with a historical behavior of the user.
7. The IHS of claim 1 , wherein the context information comprises an IHS posture, and wherein the threshold distance or time is selected as a first threshold distance or time in response to the IHS posture being a first posture or a second threshold distance or time in response to the IHS posture being a second posture.
8. The IHS of claim 1 , wherein the context information comprises an indication of whether the IHS is inside or outside of a bag, and wherein the threshold distance or time is selected as a first threshold distance or time in response to the IHS being inside the bag or a second threshold distance or time in response to the IHS being outside the bag.
9. The IHS of claim 1 , wherein the program instructions, upon execution, further cause the IHS to: receive additional context information; predict a detection of the first bidirectional wireless connection based upon the additional context information; in response to the prediction, start to scan for the first bidirectional wireless connection while maintaining the second bidirectional wireless connection; and switch to the first bidirectional wireless connection prior to dropping the second bidirectional wireless connection.
10. The IHS of claim 9 , wherein to predict the detection of the first bidirectional wireless connection, the program instructions, upon execution, further cause the IHS to determine that the IHS is moving toward a live zone with respect to the first bidirectional wireless connection using the additional context information.
11. The IHS of claim 10 , wherein to determine that the IHS is moving toward the live zone, the program instructions, upon execution, further cause the IHS to compare the current behavior of a user of the IHS with the historical behavior of the user.
12. The IHS of claim 10 , wherein the additional context information comprises an IHS posture, and wherein the program instructions, upon execution, further cause the IHS to select a first threshold distance or time in response to the IHS posture being a first posture or a second threshold distance or time in response to the IHS posture being a second posture.
13. The IHS of claim 10 , wherein the additional context information comprises an indication of whether the IHS is inside or outside of a bag, and wherein the program instructions, upon execution, further cause the IHS to select a first threshold distance or time in response to the IHS being inside the bag or a second threshold distance or time in response to the IHS being outside the bag.
14. A memory device having program instructions stored thereon that, upon execution by an Information Handling System (IHS), cause the IHS to: receive context information comprising at least one of a first user application or a second user application currently under execution by the processor; determine that the IHS is moving toward a dead zone with respect to a first bidirectional wireless connection using the context information; predict a loss of the first bidirectional wireless connection based upon a first threshold distance or time associated with the first user application or a second threshold distance or time associated with the second user application, wherein the first threshold distance or time is different than the second threshold distance or time; in response to the prediction, start to scan for a second bidirectional wireless connection; and switch to the second bidirectional wireless connection prior to losing the first bidirectional wireless connection.
15. A method, comprising: receiving context information comprising at least one of a first user application or a second user application currently under execution by the processor; determine that the IHS is moving toward a dead zone with respect to a first bidirectional wireless connection using the context information; predicting a loss of the first bidirectional wireless connection based upon a first threshold distance or time associated with the first user application or a second threshold distance or time associated with the second user application, wherein the first threshold distance or time is different than the second threshold distance or time; in response to the prediction, starting to scan for a second bidirectional wireless connection; and switch to the second bidirectional wireless connection prior to losing the first bidirectional wireless connection.
